Locking the computer
Locking the computer cover
Locking the computer cover helps prevent unauthorized access to the
inside of your computer. Your computer features a padlock loop so that
the computer cover cannot be removed when a padlock is installed.
Attaching a Kensington-style cable lock
You can use a Kensington-style cable lock to secure your computer to
a desk, table, or other nonpermanent fixture. The cable lock connects
to the security-lock slot at the rear of your computer. Depending on the
type selected, the cable lock can be operated with a key or
combination. The cable lock also locks the buttons used to open the
computer cover. This is the same type of lock used with many
notebook computers. You can order such a cable lock directly from
Lenovo by searching for Kensington at:

Replacing hardware
Before replacing hardware
Attention
Do not open your computer or attempt any repairs before reading the Important Product Information
Guide.
Read these notes before replacing hardware:
Some of the hardware components explained in this manual are optional.
Use computer components provided only by Lenovo.
When installing or replacing an option, use the appropriate instructions explained in this manual along
with the instructions that come with the option.
In most areas of the world, Lenovo requires the return of defective CRUs (Customer Replaceable
Units). Information about this will come with the CRU or will come a few days after the CRU arrives.

Replacing hardware
Handling static-sensitive devices
Do not open the static-protective package containing the new component until the defective
component has been removed and you are ready to install the new component. Static electricity,
although harmless to you, can seriously damage computer components.
When you handle parts and other computer components, take these precautions to avoid static
damage:
Limit your movement. Movement can cause static electricity to build up around you.
Always handle parts and other computer components carefully. Handle PCI/PCI-Express cards,
memory modules, system boards, and microprocessors by the edges. Never touch any exposed
circuitry.
Prevent others from touching the parts and other computer components.
Touch the static-protective package containing the part to a metal expansion-slot cover or other
unpainted metal surface on the computer for at least two seconds. This reduces static electricity from
the package and your body before you install or replace a new part.
When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package
that the part came in on a smooth, level surface and place the part on the package.
Do not place the part on the computer cover or other metal surface.

Understanding replaceable parts
Customer-Replaceable Units (CRUs)
CRUs are computer parts that a user can upgrade or replace. There are two types of CRUs: self-
service and optional-service.
Self-service CRUs You can install self-service CRUs easily. These CRUs might be standalone,
latched, or secured by up to two screws.
Examples of self-service CRUs include the keyboard, mouse, any USB device,
and the power cord. Other self-service CRUs might include memory modules,
adapter cards, hard disk drives, and optical drives.
Note
Users are responsible for replacing all self-service CRUs.
Optional-service CRUs Handling optional-service CRUs requires some technical skills and simple tools
(such as a screwdriver).
These CRUs are isolated parts within the computer. They are usually concealed
by an access panel that is secured by more than two screws. You must remove
the screws and panel to access the specific CRU.
Optional-service CRUs can be removed and installed by users or, during the
warranty period, by a Lenovo service technician.
Field-Replaceable Units (FRUs)
FRUs are computer parts that a trained technician can upgrade or replace.
For detailed FRU information, such as the FRU part numbers and supported computer models, go
to:
http:/www.lenovo.com/serviceparts-lookup
CRUs and FRUs locations
Refer to the following illustrations to check the locations of CRUs and FRUs within the computer.
